Seismic Analysis: Protecting Structures from Earthquakes

In engineering, seismic analysis is not just another requirement; rather, it is the barrier between a safe structure and disaster when the ground moves. Since earthquakes arrive without warning, designers must ensure that piping systems, storage tanks, and industrial facilities withstand the harshest seismic forces.

For more than 25 years, our team has specialized in seismic analysis. During this time, we have delivered projects that not only meet codes but also survive real earthquakes. Our experience ranges from oil refinery piping to nuclear plant equipment. Consequently, we know one truth: shortcuts are never an option.

Why Seismic Analysis Matters

Neglecting seismic analysis can result in severe consequences. However, a well-executed analysis prevents collapse, protects investments, and saves lives.

• It prevents structural failure.

• It ensures business continuity during emergencies.

• It guarantees compliance with international codes and standards.

• It significantly reduces downtime and repair costs.

Moreover, industries such as oil & gas, power plants, industrial facilities, and civil infrastructure depend on earthquake-resistant systems for uninterrupted operations.

Common Seismic Risks We Address

Earthquakes expose weaknesses that are often invisible in normal conditions. For example, piping can snap off supports, leading to ruptures. In addition, liquid sloshing may cause storage tanks to buckle. HVAC systems are also vulnerable, and their failure can shut down entire buildings. Furthermore, anchors and bolts may shear, creating dangerous weak points.

As a result, identifying and fixing these vulnerabilities in advance ensures both safety and operational continuity.

Our Seismic Analysis Process

Rather than relying on assumptions, we model, test, and validate every structure. The process unfolds step by step, with each stage adding precision and reliability.

1. Site & Load Assessment

• Collect seismic zone data

• Review soil type and foundation conditions

2. Dynamic Modelling

• Create 3D models

• Simulate realistic earthquake motions

3. Load Case Studies

• Perform static analysis

• Run response spectrum analysis

• Conduct time-history analysis

4. Stress & Movement Checks

• Measure anchor forces

• Verify pipe stresses

• Track support displacements

5. Code Compliance

• Align with ASCE 7, IBC, and API 650

• Ensure ductility so structures bend rather than break

6. Fixes & Optimisations

• Introduce base isolators where required

• Install dampers to absorb energy

• Reinforce weak supports

7. Final Report

• Provide colour-coded stress maps

• Deliver clear and cost-effective recommendations

Why Our Approach Works

Unlike conventional methods, our approach uses real earthquake records instead of purely theoretical models. Moreover, we test multiple seismic scenarios since no two quakes behave the same way. Consequently, our clients benefit from designs that balance safety with cost-efficiency—avoiding both under-design and unnecessary over-engineering.
